Homewood, once the home of Andrew Carnegie and George Westinghouse, has had more than its share of economic troubles in recent decades.

According to data available from PGHSNAP, Homewood had a population of nearly 31,000 people in 1940. By 2010, that number had decreased 79 percent to 6,442. In 2009, the median income was just under $20,000, and in 2010, 46 percent of residents were living under the poverty level.
